Just how far can you upgrade a so-called budget bike?

I guess the question is "why?"

What are you looking for it to do that it couldn't do before and have you measured the 'improvements' in any way.

E.G have you tried the old wheels and new tyres, or new wheels and old tyres...

Does the shock make it faster ?
Can you brake harder?

We've all been there and done the same, but honestly, you'd have arguably bought a better bike for less money if spending £2000 on an Ebay Santa Cruz Hightower.

Those 400-series brakes are surprisingly good eh?

I think it's a nice idea, making the kind of upgrades a new-ish rider might. Maybe share more about what it's like to ride before/after though?

Dunno much about wider range 10sp cassettes BTW, you might want to drop to a 28t ring when you change to 165mm cranks. That should be fine with a 48t biggest cog.

I think the “why” can be answered by a lot of people on STW. It’s how we be buy our bikes, can’t justify/afford a high end item so buy the bike with the best frame that we can and then upgrade and improve when things wear out and when we can afford to. 
I would have bought a Bossnut if it had just been launched a touch earlier but I’m now in fatbike nirvana!

So where are you at weight wise compared to the original bike?

Good article

Also worth mentioning that GoOutdoors often have big chunks off in their end of season sales, this bike was £1000 just b4 Xmas!

Interesting bit missing (to me anyway) is the cost of the full bike + all the upgrades Vs. a comparable full bike. I havent been bike shopping for a while, but it always used to make sense to buy the better spec'd bike upfront. Primarily because the retail cost of upgrades (even in the glory days of CRC) were not competitive.

The counterargument to that is what makes a Hightower any better?

Tyres make an actual difference. I remember the first time I bough some Maxxis super-tacky way back when and it was a whole new world, now trail tyres are almost that good in the corners.

Suspension does up to a point, but beyond the mid-range it's more 'feel' than performance.  If you're the same weight and riding style as the guy who specified it then arguably a £600 shock with all the adjusters at the mid point is no better than the £200 version that has all the same guts but no adjusters.

Brakes, sort of, but really the difference between Sub-Deore and Trickstuff is probably hundredths of a second per ride.

Wheels, no but it'll feel nicer.

Groupset, no and even the feel is marginal, does a wibbly thumb lever impact your ride? A few grams off the cassette makes the bike feel better though, but again you'll probably need something accurate than strava to see the difference.

The good news of the last ~5 years has been that ~£1500 bikes are no longer s***. I remember my Pitch (~2012) was great, but the components were awful, nothing worked after a few weeks. The wheels, brakes, headset, BB, gears, all failed. The Fox shock blew up (twice, and again for the next owner) and the fork wasn't great.  My new(ish) Vitus was cheaper accounting for inflation and apart from a few niggles (and a few known issues like the acros headset and WTB rims having a finite life) is brilliant. Apart form finishing kit I've not touched it.

Keep the comments coming. All useful. I'll be doing another update to Project Bossnut once it's 'finished' which will hopefully address most of the things mentioned so far. I'm currently 73kg or thereabouts depending on Asda's craft ale deals.

If you’ve ever been part of the Bossnut Owners Facebook group (I have as my wife had a BBB during lockdown), you’d know that this is exactly what most of the people on there were doing.
They’d bought the standard bike and then realised they enjoyed it and it rode way better than expected, they upgraded all the basic parts.

 

We never did that with her’s as it was just a stop gap while the kids were toddlers and wouldn’t ride much anyway, but were very surprised how fun and capable a bike it was (she’d come from the top spec Capra and I’d had a very tricked out Orange Alpine before then. 
Not everyone can afford a fancy bike, but many can afford a good, cheap bike and gradually upgrade it over time with nice things (and we all like nice things). 

is a HighTower better?  Maybe, is it more fun?  Maybe not.

to reduce the amount of dead-throw

Really? How does that work beyond the first ride?

Yep, I'm sure a lot of us remember saving for a low or mid-range bike, maybe with some money from parents - then upgrading bits over time from our own money.

Rims always seem to be the place manufacturers look to save money which is crazy from a performance point of view. After the tyres they are probably the most important component in terms of handling.

In fact, rims are more important than tyres. At least with tyres you know you're going to change them sooner or later.

i like this article and concept. I am much more interested at looking at something 'cheap' thats had decent upgrades than an off the shelf bling machine.

As mentioned, would be good to see if there were measurable gains by the changes/upgrades. Be that weight or a particular strava segment or route (i know thats hard to quantify with so many variables)

It doesn't on it's own, unless your brakes are over-filled and working like a set closed system brakes form the 90's.

But depending on the pad compound the coefficient of friction may decrease with temperature, so you squeeze it with less force, and thus less travel for the same level of braking. Likewise if the rotor has higher friction.

As mentioned, would be good to see if there were measurable gains by the changes/upgrades. Be that weight or a particular strava segment or route (i know thats hard to quantify with so many variables)

DIRT tried this by running bikes down a test track.  My recollection is that DH bikes could do ~1:34 ish, the best enduro bikes of the day were 1:38, and the worst on test was 1:39.  It seemed to get quietly dropped after a few issues.

Climbing exposed bigger differences but even then it seemed to just split bikes into those that could climb where the differences were seconds over ~8 minutes and those that couldn't which again all seemed to group together 90seconds down.  They could say subjective things like "this bike bobs more and as a result requires a smoother seated pedaling technique", but ultimately it would get to the top in the same time as the other bike that pedaled well out of the saddle because it was just a feeling and climbing speed was entirely down to the riders legs.

Tyres make an actual difference….

average rider here, usually riding very average bikes. Tyres and wheel make a huge difference. Wheel pickup especially. Agreed with all your points on drivetrain and then the wheel comment threw me a bit. Stick a normal stock unbranded novatech hub and unbranded rim on and replace with say a basic dt Swiss m1900 and you’ll notice a difference 100%
